STEAM VACUUM-PUMP.

Specification forming part of Letters Patent No. 103,076, dated May 17, 1870.

Improvements in Automatic Steam Vacuum- Pumps, of which the following is a speciIica-X tion z Nature and Objects of the Invention. The nature of our inventionf relates to improvements in that class of pumps known asv steam vac-uuinpumps 5' and the inventionconsists in an arrangement of valve-gear so comblned with and operated by the valves in the water inlet and outlet pipes as to operate and control the valves for the admission of steam, and for the admission of water for condensation purposes, all arranged as hereinafter fully described, for the purpose of rendering the The invention also Description of the Accompanying Drawings.

General Description.

A is a wooden tank, constructed of tapering staves, with an annular rabbet cut round infrom head to head. These are made of wood,

and are secured in place by bolts a a a screwed through the heads and into taps seated in the stays a a n. Hoops A A may be added, as desired, the object being to produce a steam-tight wooden tank capable of resisting the pressure ofthe steam from wit-hin, and of the air `from without when avacuum is formed. B is the water-inlet pipe; C, the water-outlet .pipe 5 D, the steam-inlet pipe. E is a dome or chamber seated on the top of the tank, and F a condensing water-chamber, also on the top of the tank. G is a pipe leading from the dome F to the dome E. The, steampipe D also connects with the dome E. d is a three-way cock for shutting off or making these connections, and is operated by rod d.

, ILLINOIS, ASSIGNORSL d is a piston-valve in thetop of the tank A, i

suspended in a cross-bar, 61. e is a small airpipe'leading into donne E, having a globe and check valve, c', opening inwardly. j' is a small pipe leading from the bottom of the dome F, through' thehead of tank A, and extending downward near to its bottom. It is provided with a check-valve, f', opening upward. H is a blow off pipe connecting with a pipe, h, which leads from the bottom of tank A to the water-outlet pipe C, above the discharge-valve C. cis an outwardly-opening valve in pipe H, and fv c are check-valves inthe pipe h,

opening toward the outlet-pipe C. 'Ihe valve c is operated by arms s s s, connected with dischargevalve C. J is a valve on the inletpipe B, opening upward, and connected by rod i with arm I, which, in turn, is connected with arms J J Jt, the latter two of which are slotted and slide on studs, as shown in Fig. 1. These arms are operated by the rotation ofthe rod i, consequent on the opening and closing of the valve J. d is a shaft connected at one end to the three-way cock d, and

' carrying on its other endv an arm, j, which, in

turn, carries a stud, j', working in the slot in the arm J It is also connected with a lever, M', by an arm, M. in is a rod secured to arm J working in an eye secured to standard N, which also supports these other arms and lever. L is an arm attached to the valve C', and carries on its free end a rod, L', which is provided with a hook on its upper end for the purpose of engaging with one end of the arm L, the other end of which is secured to shaft d. The domes E and F are constructed in a manner similar to tank A.

The operation of our invention is as follows: A vacuum being formed in the tank A in manner as hereinafter described, the water from the well will fiow upward through pipe B and oven valve J, which, being rigidly connected with the rod or shaft i, will, in opening, impart by its rotation a downward motion to the' connecting-arms I J' J'l J', thereby bringing down arm j, which, being connected by shaft d' with the three-way cock d, will bring said cock into position, as shown by Fig. 5, so as to shut orf the inlet of steam or water through pipes D and G, and thereby allow the tank A to lill with water. Figs. 5 and S show the relative positions of cock d and its connections at this stage ot' the operation. \Vhen the tank A is thus allowed to till with water the vacuum will be destroyed and the valve J will fall ot' its own gravity, and the weight of water above it, causing, in its downward motion, the arms I J' J" J' to move upward, and at the same time the three-way cock d is moved into the position shown in Fig. 6 by means of rod m engaging with lever M', and, by pushing its free end up, it will bring armj still further down, and thereby bring cock d into the required position so as to admit oi' the passage of thestea-m into tank A for the purpose of expelling the water through discharge-pipe C. The passage of the water through pipe C will open valve C', which, being rigidly attached to arm L, will raise rod L', with which it is connected, and cause it to engage with arm L", which, as shown, is rigidly attached to rod d'. The opening o1" valve U' will, at the same time, operate to close the valve o in pipe H by means of its connecting-arms s s' s", as shown in Fig. 3. rlhe relative positions ofthe cock d and its connections at this stage of the operation are shown by Fig. 6 and the dotted lines of Fig. S. When the bulk ot' the water is discharged from the tank A by the pressure of the steam, the steam will force a passage from the tank through the pipe L to pipe C, when, ofcourse, the valve G' will drop to its first posit-ion, bringing with it in falling its connections, whereby "mthe three-way cock d is again shifted so as to shut oft' the steam, open valve c to allow the surplus steam to blow off through pipe H, and also open communication between domes F and E, when dome F, having been supplied with water through tube f by the force of the steam, and the air therein compressed by the same force, a stream of water will be forced through pipe G into dome E, and thence into tank A, to condense the steam and form a vacuum. Figs. 7 and il and the dotted lines in Fig. 3 show the relative positions ot' cock d and its connections at this third stage ot' the operation. The effect or" forming the vacuum will be to close valves f' and o', and all communication with the interior of the tank, until it is sufficient to cause the water in the well to rise again and open valve J, and thus repeat the operation.

The construction and operation of the other parts of the invention are deemed suflciently obvious without further description.
